I do not suffer from migranes, BUT, twice this has happened; I get a headache so bad I have to go to bed. It builds up then my vision goes funny, I can't focus without an area of my vision blurring. Then, this is the bit that really scares me - my speech goes funny, I try to speak and it comes out in word that don't make sense. I know the word I want to say but I can't say it, I can't get my mouth around the word. I'm terrified. This has happened twice now. I'm 28. What could it be? Please help if you can.
This exact thing happened to me today and totally freaked me out. I had a light, throbbing headache, had some blurred vision, and for the first time ever I experienced the jumbled speech. Like you said, I knew what I wanted to say, but the words came out all jumbled. I'd be interested to hear if you ever figured this out.
